Application filed October 16, 1913. Serial No. 795,397.

To all whom it may concern:

Be it known that I,. DAVID PE'rnI-PAL- MEDO, a citizen of the UnitedStates, residing at Bridgeport, in the county of Fairfield and State ofConnecticut, have invented a certain new and useful Improvement inTypographic Composing-Machines, of which the following is a full, clear,and exact description.

This invention relates to means whereby the successive actuations of asingle key in machine will cause the release of matrices serially fromtwo or more magazine channels. Numerous mechanisms for this purpose havebeen devised; but I believe that, with all of them, the successiveactuations of the associated key causes the two escapements to bealternately operated, each through its full cycle.

The term escapements as herein used, has reference solely to themechanisms carried by the magazines for holding the matrices in themagazine channels and for releasing them one by one; and is not intendedto include either the keys or the mechanism intermediate of the keys bywhich the escapements are operated.

My mechanism is radically different in principle from all the others,because I make use of the fact that nearly all successful escapementmechanisms have a cycle of movement which includes two steps; that is tosay, they are such that the down stroke of the associated key causes theescapement mechanism to move through half of its cycle, therebyreleasing the lowermost matrix in the channel and interposing a stop inthe path of the next succeeding matrix by which the matrix column isstopped in an intermediate position; while the up stroke of the keycauses or permits the escapement mechanism to move through the last halfof its cycle,that is back to its normal position, whereby the stopreferred to is either allowed to move down, or withdrawn and the firstnamed stop moved into position, so as'to permit the matrix column tomove down to its normal position.

My mechanism is such that when the key, common to two or more channels,is depressed, it moves the escapement mechanism through the first halfof its cycle and interposes in t e path of some piece of the train ofmechanism a stop such as will hold the escapement mechanism in thisintermecapement is made diate position while the key moves on its returnstroke and until the next or some succeeding downward movement of thekev. When two escapements are to be operated alternately by a singlekey, a down stroke of said key will cause one escapement to be movedthrough the first half of its cycle with the result of releasing thematrix from the associated channel, while the other escapement which wasin the intermediate position will be permitted or caused to move throughthe second half of its cycle. If more than two escapements are to beoperated by a single key, two of them will move in the manner statedwhenever a key is depressed, but the other escapements will be in andwill remain in the intermediate position referred to, until somesucceeding actuation of the key.

The invention consists in the combination with a plurality of two-stepescapement mechanisms, and a single key, of intermediate mechanism suchthat each complete up and down movement of a key will cause oneescapement to move through only onehalf of its cycle of movement, andwill cause another escapement to move through the other half of itscycle.

The invention also consists in the more specific combinations of parts,as hereinafter described and shown in the drawing and pointed out in theappended claims.

In the drawing Figure l is a vertical sectional view of the lower end ofa magazine channel and the escapement mechanism associated therewithwhen the latter is in its normal, position, together with a sideelevation of the mechanism by which said escapement mechanism isactuated. Fig. 2 is a similar view showing the said parts in theirintermediate positions. Fig. 8 is a plan view showing two adjacentmagazines and the mechanism provided to enable a single key tosuccessively operate the escapement mechanism of said two magazines inthe manner hereinafter described. Fig. 4 is a rear elevation of theoperating mechanism for said two escapements. Fig. 5 is a plan view ofthe escapement operating shafts and the adjacent parts of the twoescapement operators.

In the exemplification of the invention which is shown in the drawing apeculiar two-step escapement is employed, which esthe subject matter ofanother application. It is to be understood, however, that any two-stepescapement mechanism might be employed in lieu of that shown, providedthat each escapement mechanism was provided with an operating elementcapable of being engaged by mechanism substantially like that shown forengaging the actuating element of the particular escapement shown.

In the escapement mechanism as shown there is a star wheel A having aplurality of arms a, a a a a. This wheel is mounted behind the magazinechannel S with which it is associated, and in a position such that oneof the star wheel arms only may be projected into the magazine channelso as to engage matrices therein. Normally one of the upper cars at ofthe matrix M rests upon that arm of the star wheel which projects intothe magazine channel.

Another arm a of the star wheel is engaged by one end of a pivoted leverB, whereby that rotation of the star wheel which would otherwise beproduced by pressure from the matrix column and which would result inthe release of a matrix, will be prevented. This lever B has three arms.The lower arm is forked and it receives one arm (Z of the escapementactuating lever D. A third arm 6 of lever B enters a notch in a lever E;and therefore all three levers must move at the same time. The lever Eis under the influence of a spring tending to mox e it and the otherlever back to their normal positions, such as is shown in Fig. 2. hen,by upward pressure against arm (Z of the escapement actuating le er D,the lever B is moved out of the path of the star wheel arm (B, the endof the lever E is moved into the path of said arm; whereupon the weightof the matrix column will turn the star wheel until arm (4 comes intocontact with the end of the lever E. In so turn ing the arm a of thestar wheel is withdrawn from the channel and thereby the lowest matrixwhich it was supporting is released. Likewise the next arm a of thestar-wheel is moved into the magazine channel beneath one of the upperears of the next succeeding matrix. The matrix column will move downuntil the said ear engages the said arm, and thereby the matrix columnis stopped. The escapement mechanism and the matrix column are now inthe intermediate position shown in Fig. 2. 1

Associated with each escapement mechanism is an operator F which is inthe form of a pivoted lever whose front end is upturned so as to be incontact with the operating arm of the escapement actuator D. A singlekey 9 is fixed to a sleeve G which is mounted on the same rod Q whichserves as the pivotal support for a row of key levers. Rigid with saidsleeve and extendassociated reeds H a pawl P in-g rearward therefrom areas many lever arms 9 as there are escapements to be operated serially.Resting on each lever arm 9 is a vertically movable reed H; and each ofthese reeds, at its upper end engages beneath an operator F.

Associated with each key, and as many escapement mechanisms as it isdesired to have a single key operate serially, is a rotatable shaft K,to which are attached as many disks N as there are escapements to beactuated serially. Each of these disks has formed in its periphery aplurality of depressions a between which are elevations n There is alsoattached to this shaft a ratchet wheel 0. There is also pivoted to oneof the adapted to engage said ratchet. By the depression of the key 9and the consequent elevation of all of the associated reeds H, the pawl,by its engagement with the ratchet, will turn the shaft through anarcual the distance between'the two ratchet teeth.

Each of the operators F has projecting laterally from one side a pin 7which overhangs and engages the periphery of the associated disk N. Whenone disk N is in a position such that the associated pin 7 of oneoperator is over a depression a therein, said operator is allowed todescend as the key makes the return movement; and the escapementmechanism associated with this particular operator is allowed to movethrough the second half ofits cycle. The various disks are set withtheir recesses in staggered relation with respect to one another, sothat when the pin of one operator F is resting in a reces n of its disk,the pins of the other associated operators are resting on the elevationsn of their disks and are held up, thereby holding the associatedescapements in the intermediate position. then therefore the key 9 is depressed, all of the associated reeds H are moved up; but since only oneof the escapement operators F is down, this one only will be moved bythe upward movement of all the reeds. This one operator will be moved upwith the result of moving the associated escapement through the firsthalf of its cycle. As the reeds move up the one carrying the pawl willturn the disk carrying shaft K so as to bring the elevated surface n onone disk N beneath the pin f of the operator which was so raised. Whentherefore the key moves on its return stroke, and the reeds move down,the particular operator which had just been elevated is held up; and theassociated escapement is left in its intermediate position. But the samearcual movement of shaft K, as just described, which moved one disk intothe position to uphold the said escapement operator, also moved anotherdisk so as to bring one distance equal to of the notches 91. thereinbeneath the pin 7 of another operator F. When the key g moves on itsreturn movement the last named operator F will move down and theassociated escapement will move through the last half of its cycle, thatis from the intermediate to the normal position.

The described mechanism is simple in construction, and permits ofindefinite expansion,-that is to say, any number of escapements may bemade to operate successively to release matrices from the associatedmagazine channels by a single key lever. Moreover the mechanism is suchthat it may be added to the ordinary escapement operating mechanism,without any change in the latter.

Having described my invention, I claim:

1. In a typographic composing machine, the combination ofa matrixmagazine having matrix holding channels, a plurality of two-stepescapement mechanisms, a single key, and means operated thereby forserially moving said escapements through the first half cycle ofmovement, and whenever an escapement is so moved, for causing anotherescapement to move through the last half cycle of its movement.
